turbo upgrade help

[chengsta]

When I was in the process of selling my '99 spyder gst I sold off my evo3 turbo. But now I've decided to keep the car and want to go with a slightly bigger turbo. I have the 50trim in mind but figure I would get some inputs before purchasing one since I don't know much about them. The HP goal I'm looking to achieve is around 350+, and happy to see the 1/4mile in low 13's maybe high 12's

The car will be daily driven to and from work but once I get it caged I'll be doing some track runs just to see what she can do. And occasionally setting the ricers around here straight that a convertible can be fast :P.

Any other turbo suggestions would be great as well. I've been out of it for a bit and only know up to a 50trim :S.
